Intervals
An interval is the distance between two pitches.
The combination of intervals in a melody gives it different shapes. These shapes can be described in a number of ways:
- conjunctA melody that moves by step.
- disjunctA melody which moves in leaps, using larger intervals than a 2nd.
- chromaticChromatic harmony uses notes from outside the key to colour the chords.
Arpeggios are rising and falling melodies that use the notes of a chord. A broken chord is the alternation of the first, third and fifth degrees of the scale. Here鈥檚 an example in the melody of a piano sonata by Wolfgang Amadeus Mozart:
